Method of doing a broadcast service of a short message in a communication system

ABSTRACT

This invention relates to the method of doing a broadcast service of a short message in a communication system. According to the present invention, a transmission request message of a broadcast message including the name and telephone number of an information provider is received from the information provider through a message center. The transmission request message of the broadcast message processed in the message center is transmitted from the message center to a base station and therefrom to all terminals. The terminals receive the broadcast message including the information provider&#39;s name and telephone number and displays them on the display devices of the terminals. When the terminal user wants to communicate with the information provider, the terminal performs the process for communication between the information provider and the user by using the received information provider&#39;s telephone number.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a method of doing a broadcastservice of a short message in a communication system.

[0002] Generally, in the service of a mobile communication system likeCDMA, the broadcast message service provided to the subscribers isprovided to the mobile terminal (or a mobile station) of saidsubscribers through paging channels and traffic channels. This broadcastmessage does not request the subscribers to answer whether or not theterminal receives the transmitted broadcast message because of itsessential peculiarities.

[0003] Three methods exist for transmitting the broadcast message bysaid paging channels. First, a multi-slot broadcast transmission methodsends the broadcast message to all slots of a control channel to sendthe broadcast message by using all the mobile terminals that are locatedin the service area of a base station. This is the simple and fastmethod having no time delay in the message. However, this method gives alarge load to the control channel and makes the process of the othermessage impossible. The second is a multi-slot broadcast paging method.This is a method improved from the multi-slot broadcast transmissionmethod. This method informs all the terminals of the broadcast bytransmitting the general paging messages of small size instead of largeto all slots of the control channel and then transmits the broadcastmessage. The third is a periodic broadcast paging method. This is themost effective method. This method informs the terminals of periodicallytransmitting the broadcast message from the base station.

[0004] After then, when a predetermined period is passed, the periodicbroadcast paging method transmits the broadcast message. The first slotof the period of which all the terminals are informed is called areference slot. During this slot, a general page message including thebroadcast address to be transmitted in future is transmitted. Throughthis broadcast address information, the terminals recognize the type andarrival time of the message and decide whether the terminals receive themessage. The broadcast message corresponding to each broadcast addressis transmitted by the period of three slots following the referenceslot. The terminal (or the mobile station) which receives the broadcastmessages by the method as described above displays the messages on itsdisplay device. The conventional techniques are the arts based on theInternational Standardization IS-637 concerned with the short messageand uses IS-95 for the radio communication of the message transmissionbetween a base station and its terminals.

[0005]FIG. 1 is a block diagram showing the network configuration of ageneral CDMA system for the broadcast service of the short message.

[0006] In FIG. 1, the base station (BS) includes the base transceiversubsystem and the base station controller. Referring to FIG. 1, themobile communication service basically using the CDMA system providesradio or wireline communication to the mobile communication subscribersby using the public switch telephone network(PSTN) 1 for the generaltelephone subscribers, which is provided by the communication networkagent, and the integrated service digital network(ISDN) 2 providingcommunication service for both voice and data by a digital subscriberline.

[0007] A mobile switching center (MSC) 3 a performs a circuit switchingand a transit paging processing so that the subscriber can communicatewith other mobile subscribers or general wireline subscribers by themobile communication service and performs the functions of hand-off androaming to provide a good quality of a communication service, and takescharge of the transport layer for the broadcast message transmission (20in FIGS. 2 and 3).

[0008] Furthermore, the base transceiver subsystem 3 b is connected withthe mobile station 4, which is either in a geostationary position or inmoving, by the radio communication path. Therefrom, the base transceiversubsystem 3 b also connects the mobile station 4 with the device in thebase station controller by radio or wireline path and takes charge ofthe relay layer 30 in FIG. 3 and 4 for the broadcast messagetransmission.

[0009] Furthermore, the base transceiver subsystem contains theinformation about various kinds of mobile communication connected withthe mobile switching center. Therefore, the base transceiver subsystemalso contains the current position information of the mobile station 4,the state of the mobile communication subscribers, the statistical dataabout the mobile communication and the information concerning to variousservices. Both the home location register 6 to be connected withradio/wireline subscribers and the visitor location register 5 to beconnected with the mobile switching center 3 a in order to search theinformation for processing the paging from other network subscribers areincluded in the base transceiver subsystem 3 b.

[0010] A cell broadcast center 7 which is an important element in thebroadcast message transmission takes charge of the teleservice layer (10in FIGS. 3 and 4). The short message entity (8) provides the broadcastmessage to said cell broadcast center 7.

[0011] The mobile communication service process of the basic network ofthe CDMA system in FIG. 1 is omitted and only the service for thebroadcast message will be explained here.

[0012] Referring to FIG. 1, a communication network agent selects one ofthe three broadcast message transmission methods by the paging channelspreviously described.

[0013] A short message entity 8 sends the broadcast message that will betransmitted to the cell broadcast center 7 which takes charge of theteleservice layer 10. The cell broadcast center 7 sends the broadcastmessage to the mobile station 4 through the mobile switching center 3 awhich takes charge of the transport layer 20 and through the basetransceiver subsystem 3 b which takes charge of the relay layer 30 shownin FIGS. 2 and 3.

[0014] Said base transceiver subsystem 3 b makes said broadcast messageincluded in the data burst message and transmits it to the mobilestation 4 through the paging channel by said selected broadcast messagetransmission method.

[0015] The multi-slot broadcast transmission method uses the data burstmessage. The remaining two methods, the multi-slot broadcast pagingmethod and the periodic broadcast paging method, use a general pagingmessage with the data burst message .

[0016] The address field in the data burst message or the general pagingmessage is filled with the broadcast address that is the address not theinborn address of the mobile station 4 but for the broadcast messagetransmission. According to this broadcast address, whether or not thebroadcast message is received is decided.

[0017]FIG. 2 shows the broadcast address for the broadcast messagetransmission in a conventional system. This address consists of twopriority bits (PRIORITY), six message identification bits (MESSAGE_ID),eight zone identification bits (ZONE_ID), sixteen service bits (SERVICE)and eight language bits (LANGUAGE).

[0018] The broadcast address will be explained as follows. The twopriority bits (PRIORITY) are to decide the priority of the broadcastmessages to be broadcast when a plurality of broadcast messages aretransmitted.

[0019] The six message identification bits (MESSAGE_ID) are to decidewhether the current broadcast message is a duplicate copy of the messagethat has already been transmitted in order to avoid a duplicatetransmission.

[0020] The eight zone bits (ZONE_ID) are to discriminate an identicalmessage received from a plurality of zones different from each other.

[0021] The sixteen service bits (SERVICE) are used to classify thebroadcast message transmission services by their items. The eightlanguage bits (LANGUAGE) are used as language indicator bits for theclassification of the languages used for the broadcast message.

[0022]FIG. 3 shows the protocol stack structure for the broadcastmessage transmission service.

[0023] The link layer 40 in the lowest level is a protocol layer forestablishing the connection of a communication circuit for thecommunication service.

[0024] Relay layer 30 of which the base transceiver subsystem 3 b ofFIG. 1 takes charge is a protocol layer to discard, when broadcastmessages having an identical broadcast address are received overlappingin time within a broadcast period, the overlapping message. Relay layer30 also takes charge of the communication path allocation, the addressestablishment and release.

[0025] Transport layer 20 of which the mobile switching center 3 a takescharge is a protocol layer for the broadcast message transmissionbetween the cell broadcast center 7 and the base transceiver subsystem 3b and takes charge of the paging connection management, dataclassification and data flow control.

[0026] Teleservice layer 10 of which the cell broadcast center 7 takescharge is a protocol layer to provide the broadcast message transmissionservice by broadcast message subparameters.

[0027] The transmission of the broadcast message provided by thebroadcast message subparameters of the teleservice layer 10 is achievedby the parameters provided from the transport layer 20), the relay layer30 and the link layer 40 which are the protocol layers lower than theteleservice layer 10.

[0028]FIG. 4 shows the broadcast message subparameters of saidteleservice layer 10. All the subparameters may be used optionally.Generally the subparameters of the broadcast message include a messageidentifier, a user data, a message center type stamp, a validityperiod-absolute, a validity period-relative, a priority indicator, analert on message delivery, and a language indicator.

[0029]FIG. 5 shows the primitive type of relay layer 30 and thetransport layer 20 in the structure of the protocol stack shown in FIG.2.

[0030] There are four steps in the primitive between said two layersthat are a request step requesting the processing of arbitrary work, anindication step informing of said requested work, a response stepresponding to said informed work, and a confirm step confirming theresponse to the request.

[0031] The relationship between the relay layer 30 and the transportlayer 20 by the primitive is explained as follows.

[0032] After the request step requesting the broadcast messagetransmission in the transport layer 20, said relay layer 30 sends anindication for informing of the broadcast message transmission to thetransport layer 20. At this time, the transport layer 20 responds so asto decide whether allowing the broadcast message transmission.

[0033] To the response, the transport layer 20 performs said broadcastmessage transmission by the confirm step of the relay layer 30.

[0034] According to the conventional arts described beforehand, thecontents ,for example a telephone number, corresponding to the receivedbroadcast message is simply displayed on the display device of theterminal. Furthermore, in the case that the subscriber who receives thebroadcast message is interested in the information of the receivedbroadcast message, the subscriber must first store the displayed number.Therefore, if the subscriber inputs the number, the subscriber isautomatically connected to the broadcast message provider and canconfirm the information.

[0035] As described beforehand, according to the conventional technique,the information of the received broadcast message is only displayed onthe LCD display of the terminal. Therefore, the following problems arepresented.

[0036] First, for the case that the sender location of the receivedbroadcast message is required to be stored in an address directory inthe terminal in order to be used in the future, the displayed senderlocation must be memorized. Then, the user must store the memorizedsender location in the address directory by using a separate process ofthe terminal.

[0037] Second, if the user wants to confirm the information of thereceived broadcast message, the user must memorize the previouslydisplayed telephone number. Then, the user has to input the memorizedtelephone number by the keypad and make the connection with theinformation provider of the broadcast message. Therefore, memorizing anddialing the previously displayed telephone number must be vexatiousprocesses

[0038] Third, because of the above two inconvenient processes, thequality and efficiency of the broadcast service of the originallyplanned short message can decrease.

SUMMARY OF THE INVENTION

[0039] Accordingly, the present invention is directed to provide amethod of doing the service of broadcast message in a communicationsystem such that a terminal user can communicate easily and convenientlywith the information provider such as the service agent providing adesired broadcast message.

[0040] Another object of the present invention is to provide a method ofdoing the service of the broadcast message in a communication system bywhich the terminal user easily stores the telephone number and name ofthe information provider in the address directory in the terminal so asto use it in the future.

[0041] To achieve these and other advantages and in accordance with thepurpose of the present invention, as embodied and broadly described, twosubparameters for the broadcast message are used additionally in thepresent invention.

[0042] One subparameter, the third party call name, is used forinserting the name of the information provider. The other subparameteris the third party call number for inserting the telephone number of theinformation provider.

[0043] The cell broadcast center makes the name and telephone number ofthe information provider who requests the transmission fo the broadcastmessage included in the broadcast message by using the two subparameters(the third party call name and the third party call number). Theterminal decides whether or not there are the two subparameters in thebroadcast message when receiving the broadcast message. Therefore, inthe case that the subparameters are included in the broadcast message,the terminal takes the processes for achieving the above objects.

[0044] According to the present invention, in the case that the cellbroadcast center receives the transmission request message of thebroadcast message including the name and telephone number of theinformation provider from the information provider, the name and thetelephone number are inserted in the two subparameters (third party callname, third party call number), respectively.

[0045] The broadcast message having the two subparameters in which thename and the telephone number of the information provider are included,respectively, by the cell broadcast center is transmitted to allterminals through the base transceiver subsystem.

[0046] When the terminal receives the broadcast messages having thesubparameters in which the name and telephone number of the informationprovider are included, the terminal displays the contents, the telephonenumber and the name in the subparameters of the broadcast message on itsdisplay device in a certain sequence.

[0047] When the terminal user wants, the terminal performs the processfor establishing the traffic channel between the information providerand the terminal user by using the telephone number of the receivedinformation provider.

[0048] Therefore, when the service agent transmits advertisements andpublic information by using the service of the short message, theterminal user can easily communicate with the information provider ofthe broadcast message that the user wants. Furthermore, to use them inthe future, the telephone number and the name of the information can beeasily stored in the address directory of the terminal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0059] Reference will now be made in detail to the preferred embodimentsof the present invention, examples of which are illustrated in theaccompanying drawings.

[0060] For the explanation of the present invention, figures usedbeforehand for explanation of the conventional techniques can be used.

[0061]FIG. 6A is a table showing the subparameters of the broadcastmessage according to the present invention. The table in FIG. 6A has thesame subparameters as the conventional broadcast message in FIG. 4except two subparameters, the third party call number and the thirdparty call name. In the present invention, the new two subparameters(the third party call number and the third party call name) are added tothe broadcast service format of the short message used for thetransmission of the broadcast message in the teleservice layer 10 ofFIG. 3. As explained beforehand, the broadcast message is transmittedfrom the base station 3 to the mobile station. Prior to this, in orderto realize the present invention, when the information provider such asthe service agent wants to transmit the information, for example thesender name and the message sender location such as the telephonenumber, the information together with the transmission request messageof the broadcast message is transmitted to the cell broadcast center 7of FIG. 1. The cell broadcast center 7 makes the name (for example, afirm name) and telephone number of the information provider insertedinto the broadcast message of the information provider by using theadded two subparameters (the third party call number and the third partycall name)

[0062] The broadcast message process procedure in the cell broadcastcenter 7 for realizing the present invention is explained as follows.First, the cell broadcast center 7 receives the transmission requestmessage of the broadcast message from the information provider such asthe service agent. Then, the information provider transmits thetelephone number and the name together with the information. The cellbroadcast center 7 determines whether the information provider requeststo transmit both the telephone number and the name together with theinformation of the broadcast message. If the information provider wantsto transmit both the telephone number and the name, the cell broadcastcenter 7 inserts the telephone number and the name into twosubparameters, the third party call number and the third party callname, respectively. After then, the cell broadcast center 7 transmitsthe transmission request message of the broadcast message including thetwo subparameters (the third party call number and the third party callname) to the base station 3 of FIG. 1. The base station 3 transmits thereceived transmission request message of the broadcast message to themobile station 4. In other words, if the cell broadcast center 7receives a bearer information of the short broadcast message includingthe telephone number and the name from the information provider, whenthe broadcast message of the teleservice layer is constructed, thetelephone number of the information provider is included into thesubparameter third party call number and the name of the informationprovider is included into the subparameter third party call name. Afterthen, the transmission request message of the broadcast message istransmitted to the base station 3 of FIG. 1.

[0063]FIG. 6B is a table showing the subparameters of the broadcastmessage according to the present invention. The table in FIG. 6B has thesame subparameters as the conventional broadcast message in FIG. 4except one subparameter, the third party call number. In the presentinvention, the new subparameter (the third party call number) is addedto the broadcast service format of the short message used for thetransmission of the broadcast message in the teleservice layer 10 ofFIG. 3.

[0064] On the other hand, the base station 3 transmits the broadcastmessage requested by the cell broadcast center 7 to all the terminals 4through the control channel (paging channel) and the traffic channel.

[0065] Referring to FIG. 8, the process for the subscriber terminal(mobile station) 4 to receive the broadcast message from the basestation 3 is explained as follows.

[0066] The terminal 4 decides whether there are two subpararmeters forthe third party call number and the third party call name, or one ofthem.

[0067] Whether these two subparameters are added or one of them is addedis the provider's option. If the subparameters are not included, theterminal 4 performs a general process for the received broadcastmessage. For example, if the subparameters (the third party call numberand the third party call name) are in the broadcast message, theterminal 4 displays the contents of the broadcast message, the telephonenumber and name of the information provider on the display device in acertain sequence. In order to display the information, four sequencesmay be considered. As the first example, the terminal 4 displays thecontents of the broadcast message on the display device (for example,liquid crystal display) and then displays alternately the telephonenumber and name of the information provider included in thesubparameters (the third party call number and the third party callname) after a constant time (for example, one or two seconds) is passed.As the second example, the contents of the broadcast message and boththe telephone number and the name of the information provider may bedisplayed on the display device at the same time. As the third example,the contents of the broadcast message are first displayed on the displaydevice and after then, both the telephone number and the name of theinformation provider may be displayed on the display device at the sametime. As the fourth example, the name of the information provider isfirst displayed on the display device and then the contents of thebroadcast message may be displayed on the display device. Hence, theterminal 4 decides whether the user or the service subscriber pressesthe communication key on the keypad. Any key may be assigned to thiscommunication key by the terminal provider. This communication key is tobe used when the service subscriber of the terminal side wants tocommunicate with the information provider by using the telephone numberof the information provider who provides the broadcast message.Therefore, if the communication key is pressed by the servicesubscriber, the telephone number of the information provider is insertedinto the field parameter (called number) of the origination message.This origination message is transmitted from the terminal (mobilestation) 4 to the base station 3 of FIG. 1. The base station 3established a traffic channel between the service subscriber of theterminal side 4 and the information provider. The process forestablishing the traffic channel is performed according to thestandardization without any relation to the present invention andtherefore the explanation for the establishing process is omitted here.

[0068] On the other hand, if the communication key is not pressed by theservice subscriber even though the telephone number and the name aredisplayed, the terminal 4 checks whether or not the subscriber pressesthe store key on the keypad. This store key may be assigned by theterminal provider. This store key is used for the service subscriber tostore the telephone number and/or the firm name of the informationprovider included in the subparameters (third party call name and thirdparty call number) in the address directory of the terminal 4 so thatthe service subscriber can communicate with the information provider inthe future. The name (or firm name) is stored in the name field of theaddress directory and the telephone number is stored in the numberfield. Therefore, as in FIG. 8, when the service subscriber presses thestore key, the telephone number and the name of the information providerare stored in the address directory of the terminal 4. Then, thetelephone number of the information provider may optionally be stored inthe address directory or both the telephone number and the name may bestored. According to the present invention, the following effects may beobtained.

[0069] There may be the case that the subparameter third party call nameto insert the name of the information provider does not exist in thebroadcast message received by the terminal. This may be the case thatthe information provider of the broadcast message does not provide thename by mistake or on purpose intentionally when the provider transmitsthe transmission request message of the broadcast message to the cellbroadcast center.

[0070] In this case, the terminal user may press the store key when theuser wants to store the name as well ad the telephone number of theinformation provider. However, this is the case that the subparameterthird party call name does not exist in the received broadcast message.If the result of the process for the terminal 4 to check whether or notthere is the subparameter third party call name in the receivedbroadcast message is that the subparameter does not exist, the terminalextracts the first ten bytes of the subparameter (user data) includingthe broadcast message content among the subparameters shown in FIG. 6and then stores the data of the extracted ten bytes in the name field ofthe terminal address directory. Therefore, for this case, without regardto whether or not the subparameter (third party call name) exists, it ispossible to store the telephone number in a classified order. Therefrom,the terminal user can easily find the telephone number that the userwants from the address directory.

[0071] First, when the service subscriber of the terminal 4 side wantsto communicate with the provider of the broadcast message, by simplypressing the communication key, the subscriber can easily make thecommunication.

[0072] Second, by simply pressing the store key, the subscriber canstore the telephone number and the name of the information provider inthe address directory of the terminal.
